This movement of carbon from one place to another, which is caused by natural and human processes, is known as the carbon cycle. The oceans play a particularly important role in the carbon cycle. Surface waters exchange gases with the atmosphere, absorbing and releasing carbon dioxide, oxygen, and other gases. Plant-like phytoplankton living in ...
Carbon is a building block for all life and plays a key role in regulating Earth’s climate. It shuttles throughout the planet in two major cycles. The first is the biospheric carbon cycle. Plants convert carbon dioxide from the air into organic carbon compounds (biogenic carbon). Microbes decompose plants and animals, releasing carbon dioxide ...
There is 50 times as much carbon in the ocean as in the atmosphere. Plants link the earth’s inorganic and organic carbon cycles by capturing inorganic carbon dioxide gas and turning it into organic forms of carbon that other organisms can use. Microscopic plants in the ocean conduct half of the photosynthesis.
While river transport of carbon to the ocean is not on a scale that will bail humans out of our CO 2 problem, we don’t actually know how much carbon the world’s rivers routinely flush into the ocean – an important piece of the global carbon cycle. But in a study published May 14 in the journal Nature, scientists from Woods Hole ...

This complex carbon-transporting ocean process, often called the “biological pump,” is a critical mechanism in preventing what we now know as the “greenhouse effect,” the collection of gases in the atmosphere that hinders upward transport of heat. Understanding of Earth’s carbon cycle is one of humankind’s great scientific questions.
The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. The confluence of tectonically exhumed mantle rocks and CO2-rich alkaline basalt formed through limited extents of melting characteristic of the St. Paul’s transform faults may ...
The BCP is not a single process, rather it is a collective of processes that synergistically influence the transport of carbon deep into the ocean that in turn helps regulate global climate.21 Essentially, there are three major pathways that comprise the Biological Carbon Pump (BCP): 1. Gravitational Pump, 2. Mixing Pump, and 3. Migrant Pump.
When phytoplankton die or are eaten by zooplankton, the carbon-rich fragments sinks deeper into the ocean, where it is, in turn, eaten by other creatures or buried in sediments. This process is key to the “biological carbon pump,” an important part of the global carbon cycle.
The removal of CO₂, its conversion to organic carbon, and the carbon’s dispatch to the ocean’s depths is known as the ocean’s biological pump. “If you turned off this biological carbon pump—let’s say, you somehow made the ocean sterile and sucked out all of the twilight zone’s organisms—you would more than double the amount of ...
